| 摘 要： | 针对磁路饱和对同步磁阻电机运行特性的影响,提出了定子电流最优控制策略。通过有限元法对电感与电流的非线性关系进行拟合,并利用拟合结果得到最优定子电流随转矩变化的运行轨迹,以实现同步磁阻电机最大转矩电流比(MTPA)控制；同时对于交直轴电流环相互耦合的问题,提出磁路饱和补偿的电流环设计,以提高其动静态性能。仿真与试验结果验证了该方案的有效性。

| Abstract: | The optimal stator current control of synchronous reluctance machine (SynRM) considering magnetic saturation was proposed. With the finite method, the nonlinear relationship between current and inductance obtained, and then the optimal trajectory of stator current changing with load was got to realize maximum torque per ampere (MTPA) control; As to the coupling problem of traditional current loop, decoupling control considering magnetic saturation was proposed to improve the dynamic and static performance. Simulation and experimental results verified the effectiveness of the scheme. |
